Installation summary

This genuine BMW CSL 22.5mm rear sway bar kit installation is rated as Medium difficulty and requires advanced DIY skills and familiarity with suspension components; professional installation is recommended for those unsure. You will need standard metric socket and wrench sets, a torque wrench, and potentially a pry bar for leverage, along with jack stands and wheel chocks for safety. The most critical aspect of this installation is ensuring the new sway bar is properly seated in its bushings and that all hardware is torqued to BMW's specifications to prevent noise and ensure optimal performance. An alignment is required after installation, and if you have adjustable coilovers, you may need spring perch adjustment tools to set your desired ride height.
